Ashcroft T424T10030BX205 Temperature Switch 75-205F

Product Description

The ASHCROFT T424T10030BX205 is a watertight single setpoint temperature switch designed for industrial and commercial process control applications. It uses a 10-foot capillary stem to sense temperature at a remote point and actuate an electrical circuit when the process reaches the configured setpoint. The adjustable range spans 75 to 205 degrees F, making it suitable for liquid or gas media monitoring in HVAC, boiler, and fluid process systems. The watertight housing protects internal contacts from moisture ingress, supporting reliable operation in wet or outdoor environments. Licensed technicians and instrumentation professionals are the primary installers of this device.

This temperature switch is applied in residential and commercial HVAC systems, hot water heating loops, industrial fluid lines, and process equipment where remote bulb sensing is required. The 10-foot capillary allows the sensing bulb to be positioned directly in the process media or pipe while the switch body is mounted in a convenient, accessible location. It is well suited for freeze protection circuits, high-limit cutouts, and process on-off control within the 75 to 205 degrees F operating band.

Key Features

• Adjustable single setpoint across a 75 to 205 degrees F temperature range
• 10-foot capillary stem for remote bulb sensing and flexible mounting
• Watertight enclosure construction resists moisture ingress in wet or outdoor installations
• Single setpoint design simplifies wiring and control circuit integration
• Package quantity of 1 unit per order

Compatibility

Designed as an OEM-style replacement or new-installation temperature switch for commercial and industrial process control applications requiring a capillary-type single setpoint switching device with a 75 to 205 degrees F range.

Installation Notes

Installation should be performed by a licensed HVAC technician, plumber, or instrumentation technician familiar with temperature control circuits. De-energize the control circuit and isolate the process line before installing or removing the sensing bulb. Route the capillary carefully to avoid sharp bends, kinks, or contact with high-heat surfaces that could damage the capillary tubing. Wiring must comply with applicable NEC requirements for the circuit voltage and environment classification.
